I would love to say Franklin outright, but Jardine is such a tricky little bastard with his striking style and those disgusting leg kicks, that I think that it's basically a toss up. I do give the enormous size advantage to Jardine and I think that his style might slip up Franklin.
As I'm writing this, I'm thinkin Jardine because of that Chuck fight and how much he impressed me then and also, the way he totally shocked Forrest.
Franklin is a very skilled fighter, but Jardine always cooks up some wacky game plan when he's fighting somebody that good and I find he FIGHTS up or down to the level of his competition.
He fights up when he's got nothing to lose and down when he think's he's got in it the bag like the Alexander fight.
Jardine, but really, toss up.
